Device for Storing and Dispensing Food Items

ABSTRACT

A device for storing and dispensing food items for a customizable nutrition supply is provided. The food items are loaded by the user, allowing customization of nutritional content and sequence. The device may be portable and operated with one hand, and is sufficiently sealed to store the food items securely, away from air, dust, and moisture. When the device is operated by being opened or triggered, it dispenses the next food item, so that the user may dispense the food item directly into the user&#39;s mouth. The device then closes or is closed.

FIELD OF THE INVENTION

The presently disclosed subject matter relates to storing and dispensing food items, and more specifically, to devices and methods for portable storage containers that protect food items, and that dispense the food items individually.

BACKGROUND OF THE INVENTION

People engaged in high-performance endeavors and endurance sports, such as triathlons, long-distance running, and long bicycle rides, have significant needs for nutrition during their competition or performance. In the course of a 50 km run or a 100 mile bike ride, a 160-lb person may burn 600 to 800 calories per hour. Furthermore, a person's nutritional needs are not limited solely to replacement of calories expended in the endeavor: endurance athletes also need to replace particular types of nutrition, and may need them at specific stages of the workout or competition. For example, an endurance athlete may need some fat content in his or her food at the start of a long workout, a higher percentage of carbohydrates in the middle, and proteins at the end for an effective recovery. Based on an individual's size, gender, and level of exertion during an athletic effort, and based on environmental conditions, people will have different nutritional needs, both in terms of quantity and content of food.

The current state of food marketed to athletes does not fully meet these needs. Most food items targeted to athletes are based on technology of processed food, specifically that of taking a mixture of food items and forming it into a bar shape. Some such products, often referred to generically as energy bars, are shaped more like traditional chocolate bars and others like thicker granola bars, while some are smaller bite-sized pieces, and still other products are more like a viscous goo and not a solid or malleable bar. These nutritional items fall short in several ways in the context of athletic competitions, and especially in endurance athletics.

One shortcoming of the current food technologies is that it can be difficult to take in sufficient calories with the currently existing energy bar products. A typical energy bar contains 200 to 250 calories, and a person, for the purposes of example only, such as a 160-lb pound male playing basketball or boxing, engaged in a typical athletic effort may burn 600 to 800 calories per hour, while a person in an endurance event may burn 600 to 1,000 calories (for example, refer to research by, Dr. Edward Howley, Professor of Health and Exercise Science at the University of Tennessee, available at http://hes.utk.edu/f_s/howley.html). The need to carry and keep organized multiple nutrition sources is difficult for people engaged in high-performance endeavors. Second, such nutritional sources are typically sealed in high-barrier films, which are most easily opened with two hands. When engaged in a competition, or a non-competitive but demanding event, it may be difficult or impractical to use both hands to open an energy bar. Attempting to open such a nutritional product using only one hand is quite difficult, and using only one hand plus one's teeth is challenging and unhygienic, and can often result in the loss of the energy bar. Additionally, serious injuries can result from a loss of concentration or control when a user is distracted with an attempt to open a bar, whether the user is bicycling, running, or engaged in another activity.

Third, using current nutritional products, it is very difficult to customize one's food intake. A user can customize the amount eaten, such as by cutting the bars up in advance, or eating portions of a package, but not the content of an individual bar, and so it is difficult or impossible to customize an order of nutrition, such as fats, then carbohydrates, then protein. Further, even if it is possible to find an arrangement of energy bars or other relatively suitable foods that would provide a desired order of nutrition, attempting to stack them in order in a bag or pocket would be cumbersome. Repeatedly finding the right bar and then opening it would be prohibitively challenging, especially in the context of an activity where opening a single bar is difficult. The ability to customize nutritional content and the order in which one eats the food items is lacking in the current art. Also lacking in the current art is a way to securely store, carry, and dispense food using only one hand.

SUMMARY OF THE INVENTION

The present invention meets all these needs, by disclosing devices and systems for storing, protecting, and dispensing food items. The device comprises a dispenser which may be opened and loaded with food items, so that a user can place food items into the device for later dispensing and consumption. The user can choose the content of the nutrition to be consumed by choosing particular food items, and can customize the order of nutrition to be consumed by placing the food items in any particular order. Once closed, the device securely stores and protects the food items, keeping them free of dust and moisture.

The device can be loaded with sufficient calories to offset the calorie deficit created by activity and support a person engaged in an extreme or endurance event, such as a triathlon, marathon, or any athletic activity that creates a calorie deficit. The present invention is simple to operate, in contrast to the current art relating to energy bars and other foods intended for athletic and endurance endeavors.

The present invention allows only one disc (a food item) to be dispensed per actuation. The device advances another disc into the ready position. This cycle can then be repeated until the device is empty. In various embodiments, the device may have a trigger mechanism actuating an ejector and opening a dispenser slot cover, so that when the user presses the trigger, the device's dispenser slot cover opens, a food item is ejected, and the cover then closes and the device advances all the remaining food items, so that the next one is ready for dispensing. It has been found advantageous to all the user to hold the device in one hand and activate the trigger using a finger or the thumb of that hand. The food item may be dispensed directly into the user's mouth, so that true one-handed operation is possible. This is a necessary feature for many use cases of the present invention, such as bicycling, in which a user may want to keep one hand on the handlebars and use the other to pick up the present invention and dispense a food item directly into the user's mouth. This one-handed system also allows users to leave their gloves on and still eat, which is important for winter sport athletes such as alpine skiers, cross-country skiers, snowboarders, and others.

Furthermore, the present invention can be used to customize the nutritional profile that a user takes in, by loading food items with different caloric and nutritional content into the device in any order. In this way, the present invention can be used to supply the user with a desired amount, order, and mix of food and nutrition, and can deliver it directly to the user for one-handed consumption without significant risk of dropped or lost food.

These aspects of the present invention, and other disclosed in the Detailed Description of the Drawings, represent improvements on the current art. This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description of the Drawings.

DETAILED DESCRIPTION

The presently disclosed invention is described with specificity to meet statutory requirements. But, the description itself is not intended to limit the scope of this patent. Rather, the claimed invention might also be embodied in other ways, to include different steps or elements similar to the ones described in this document, in conjunction with other present or future technologies. Moreover, although the term “step” may be used herein to connote different aspects of methods employed, the term should not be interpreted as implying any particular order among or between various steps herein disclosed unless and except when the order of individual steps is explicitly described.

The present subject matter discloses devices and systems for storing, protecting, and dispensing food items. It has been found advantageous to have, as shown in FIG. 1, the present invention comprise a device 100 for storing and dispensing food items for a customizable nutrition supply, in which the device comprises a container 102 that is approximately cylindrical in lateral cross-section perpendicular to the long axis 104, though the lateral cross-section need not by identical along the length of the long axis 104 of the container 102. In other embodiments, the container 102 may be triangular, rectangular, or another shape in lateral cross-section and may have one or more sidewalls 106 that define the outside of a cylinder, or that are planar and perpendicular to a lateral cross-section, creating a container 102 shaped like a triangular or rectangular prism. In still other embodiments, the container 102 may have sidewalls 106 that are not planar but instead are curved or faired. In yet other embodiments, such sidewalls 106 may not be identical to each other. The sidewalls 106 of the container 102 together with the top cap 108 and bottom cap 110, if present in that embodiment of the present invention, form the exterior of the device 100. It has been found advantageous to have the container 102 comprise a solid surface, exclusive of openings including but not limited to those for loading food items 112 and dispensing food items 112, as described below. In some embodiments, it is desirable to build the device 100 with a container 102 that has one or more openings or perforations.

The container 102 may, in some embodiments, have a dispenser opening 114 positioned on the container towards or at the top or bottom of the container 102, through which the food items 112 may be dispensed, as discussed in more detail below. The dispenser opening 114 may, in some embodiments of the present invention, be positioned on the side of the container 102 so that the longer dimension of the dispenser opening 114 is oriented perpendicular to the long axis of the container 102, and so the smaller dimension of the dispenser opening 114 runs parallel to the long axis of the container 102, and may be sized to be large enough to allow just one of the food items 112 through at one time. In other embodiments, the dispenser opening 114 of the container 102 may be a top cap 108 or other part that opens to dispense food items 112, or though which one or more of the food items 112 may be retrieved by the user.

The device 100 has one or more food item advancers 116 which may be any one or more of a tension spring, a compression spring, a torsion spring, or other spring types. The food item advancer 116 may be affixed at or near the bottom of the container 102 or to the bottom cap 110 to one or more food item advancer attachers 124, and to a pusher plate 118. The food item advancer 116 is compressed as the food items 112 are loaded, and then the food item advancer 116 push the pusher plate 118 which pushes the food items 112 toward a top dispenser opening 114 or an openable top cap 108 for dispensing the food items 112. In other embodiments, the food item advancer 116 may be attached to food item advancer attacher 124 at or near to the top of the container 102, and then extended as the food items 112 are loaded, so that the food item advancer 116 pull the pusher plate 118 and thus the food items 112 up towards the dispenser opening 114 or openable top cap 108. In still other embodiments, the dispenser opening 114 may be at the bottom of the container 102, and the food item advancer 116 may then be attached at or near the top or bottom of the container 102 to, respectively, push or pull the food items 112 down towards the bottom dispenser opening 114.

In still other embodiments of the present invention, as shown in FIG. 2, the food item advancer 116 may be a constant-force spring assembly 202. In this or other embodiments, the container 102 may have pusher plate alignment guides 230 on the sides of the container, and the pusher plate 118 may have a plurality of pusher plate aligners 232 that slidably engage with the pusher plate alignment guides 230, allowing the pusher plate 118 to slide up and down inside the container 102 on the pusher plate alignment guides 230. The top cap 108 may be removably engaged with the pusher plate alignment guides 230, held by friction or other means, or the top cap 108 may have a top cap aligner 240 to ensure only one alignment is possible with the container 102. The constant-force spring assembly 202 may be contained inside of the top cap 108.

The constant-force spring assembly 202 may comprise a constant-force spring 204, a spring spool 206, a spring housing 208, and a string 210. The spring housing 208 may be a cylinder, with a housing floor, a housing top, and housing sides, and the spring housing 208 is held in place in the container 102 by the pusher plate alignment guides 230, by friction or other means. The spring housing 208 also has a housing post 212 in its center, extending from the housing floor to the housing top. The spring housing 208 also has a housing string hole 214 in the housing sides.

The spring spool 206 is located inside of the spring housing 208. The spring spool 206 may be roughly a cylinder, with a spool floor, a spool top, and spool sides, and may have spool rims 216 defined by the diameters of the spool top and spool floor, which may be equal to each other and larger than the exterior diameter of the spool sides. The housing post 212 passes through the spring spool 206, allowing the spring spool 206 to spin freely within the spring housing 208. The spring spool 206 also has a spool string hole 218 in the spool sides.

The constant-force spring 204 sits inside of the spring spool 206, with the constant-force spring 204 attached to the housing post 212 at or near the innermost part of the constant-force spring 204. At the outermost part of the constant-force spring 204, the string 210 is attached to the constant-force spring 204. The string 210 passes through the spool string hole 218, is wound around the spring spool 206 one or more times, where it is constrained from slipping off of the spring spool 206 by the spool rims 216. The string 210 then passes through the housing string hole 214 and then through the trigger assembly string hole 404 of the trigger assembly 400, described below, and along the outside of the stack of the food items 112 without making contact with the food items 112. In this or other embodiments of the present invention, the pusher plate 118 may have a pusher plate string hole 224, and the string 210 may pass from the trigger assembly string hole 404 to the pusher plate string hole 224. In some embodiments, the pusher plate 118 may have two or more pusher plate string holes 224, and the string 210 may pass from the trigger assembly string hole 404, through one pusher plate string hole 224, under or the pusher plate 118 or through a channel in the pusher plate 118, through the other pusher plate string hole 224, and up along the opposite side of the stack of food items 112 to attach to a fixed point in the device 100, which may be the container 102, the spring housing 208, or other suitable point as will be apparent to one of skill in the art, in order to prevent the pusher plate 118 from twisting inside of the container, and/or to ensure a smooth operation of the constant-force spring assembly 202 as the food item advancer 116.

In some such embodiments of the present invention, when the trigger assembly 400 is operated by the user and rotates about the location of the trigger assembly placement 302, as shown in FIG. 3, the trigger assembly 400 pinches the string 210, preventing it from pulling up the pusher plate 118 while the trigger assembly 400 is dispensing one of the food items 112, as described in greater detail below. When the trigger 402, as shown in FIG. 3 and in greater detail in the views of the trigger assembly 400 in FIG. 4, is released or returned to its rest position, the trigger assembly 400 rotates back and releases the string 210 from being pinched. The constant-force spring 204 then coils more, as the topmost of the food items 112 has been dispensed, pulling the string 210 which pulls the pusher plate 118, advancing the stack of food items 112 and moving the next of the food items 112 into the ready position, to be dispensed next.

In other embodiments of the invention, there are rocker arms 128 affixed to the interior of the container 102, and which are constructed as elastically attached to or part of the container 102, such that the rocker arms 128 may be moveably engaged against the food items 112 or may be pushed out of the way of the food items 112. When the top cap 108 is open, as shown in FIG. 5A, the rocker arms 128 spring in towards the interior of the container 102, and pinch in to the food items 112 or into space between food items 112. The rocker arms 128 are positioned to pinch into the second of the food items 112 in the stack, or into the space between it and the first of the food items 112. This allows the first of the food items 112, in the so-called “ready position”, to be dispensed, in this embodiment by the user grabbing the topmost of the food items 112 or by shaking it or tipping it out of the container 102, while the second and the rest of the food items 112 are blocked from advancing. When the top cap 108 is closed, as shown in FIG. 5B, the pry arms 502 come into contact with the rocker arms 128, and push the rocker arms 128 elastically towards the sides of the container 102, so that the rocker arms 128 are no longer preventing the food items 112 from advancing. By means of the rocker arms 128, the food item advancer 116 is controlled to advance the food items 112 towards the dispenser opening 114 by only one of food items 112, that is, by a distance equal or nearly equal to the thickness (in the direction of the long axis 104 of the container 102) of only one of the food items 112. The top cap 108 is shown in more detail in FIG. 5C, FIG. 5D, and FIG. 5E, showing the pry bars 502, the cover hinge 504 that is present in some embodiments of the invention and is rotatably engaged with the container opening hinge 130 that is present in some embodiments, and the cover catchment 506 that is present in some embodiments, and which engages with the cover closure mechanism 132 that is present in some embodiments.

It has been found advantageous in the present invention to have the device 100 further comprise a pusher plate 118 attached to the food item advancer 116 at the end of the food item advancer 116 distal to the food item advancer attacher 124, for instance if the food item advancer 116 is to push the food items 112 toward the dispenser opening 114. As will be apparent to one skilled in the art, in some embodiments of the present invention, it may be desirable to have the pusher plate 118 attached to the food item advancer 116 proximal to the food item advancer attacher 124. It has been found advantageous to have the pusher plate 118 comprise a flat or approximately flat piece shaped roughly like the cross-sectional profile of the container 102.

It has been found to be advantageous to have the pusher plate 118 further comprise one or more pusher plate catchments, and the container 102 has one or more pusher plate retainers that align with the pusher plate catchments. The container 102 may also comprise one or more pusher plate catchment release mechanisms, which are operated by the user with catchment release mechanism actuators on the outside of the container 102. The catchment release mechanism actuators may be buttons, levers, or other means. In alternative embodiments, the container 102 may have an opening for the user to directly actuate the pusher plate catchment release mechanisms.

In some embodiments of the invention, the pusher plate 118 further comprises a plurality of pusher plate aligners 232, and the container 102 has one or more pusher plate alignment guides 230 that align with the plurality of pusher plate aligners 232. The plurality of pusher plate aligners 232 may be protrusions, bumps, slots, or other suitable means of slidably engaging with the pusher plate 118, to guide it as it is pushed or pulled by the food item advancer 116, along the pusher plate alignment guides 230, which may be slots, tracks, or other suitable means.

In some embodiments of the invention, the pusher plate 118 and food item advancer 116 are placed by the user in the container 102, and then latched into place by pusher plate retainers at the end of the container proximate or distal to the dispenser opening 114, allowing the user to easily load the food items 112 individually or in a stack in such an order that they are lined up to be dispensed in the order desired by the user. In some embodiments of the invention, a latching bottom cap 110 may be placed and latched on the bottom of the container 102, and the food item advancer 116 and pusher plate 118 then inserted from the top cap 108, aligned with the pusher plate alignment guides 230, with the food item advancer 116 then compressed or moved to the bottom of the container 102, at which point the pusher plate catchments are engaged with the pusher plate retainers, locking the pusher plate 118 and allowing loading of the food items 112. The bottom cap 110 may be affixed to the container 102 by means of protrusions 120 that fit into slots 122 in the container 102, or the bottom cap 110 may be threaded to match threads on the container 102, so that the bottom cap 110 screws on. In other embodiments of the invention, the food item advancer 116 may be affixed to a latching bottom cap 110 and then inserted into and latched to the container 102, and thereafter the user may insert the pusher plate 118 into the container 102. In some embodiments, the pusher plate 118 has pusher plate catchments which engage with the pusher plate retainers, locking the pusher plate 118 and allowing loading of the food items. In still other embodiments of the present invention, a user may load a stack of food items 112 into the container by creating the stack and then placing the container 102 over it, or by other means. In any of these embodiments or others, the bottom cap 110, food item advancer 116, and pusher plate 118 may be affixed together by means of screw threads or clips, and then may be attached to the container 102 by any means as described herein for attaching the bottom cap 110, or other means. As will be apparent to one of skill in the art, other arrangements are possible, and those provided here are by way of illustration only, without limiting the subject matter claimed.

It has been found to be advantageous in the present invention to have the dispenser opening 114 optionally closed off by means of a dispenser cover 406 which is sized and shaped to fit and seal the dispenser opening 114. The dispenser cover 406 functions to keep moisture, dust, and air out of the interior space of the container 102 and away from the food items 112. In some embodiments of the present invention, the dispenser cover 406 may be seated in its sealed position against a gasket of silicone, rubber, or other suitable material placed around or inside of the dispenser opening 114. In embodiments where the dispenser opening 114 is in the side of the container 102, the dispenser opening 114 may be configured to open by rotating around the long axis 104 of the container 102, or may be configured to slide up or down parallel to the long axis 104. In either of the foregoing embodiments, the dispenser cover 406 may be configured to open to the inside or outside of the container 102, and may be configured so that it closes and seals the dispenser opening 114 while slightly biased to the inside or outside of the outer surface of the container 102, or so that the dispenser cover 406 seals the dispenser opening 114 and is flush with the outer surface of the container 102.

In embodiments of the present invention where the dispenser opening 114 is part or all of the top cap 108 or bottom cap 110 of the container 102, the dispenser cover 406 may be configured to flip open, with one edge or side hinged to the container 102, and the opposite edge of the dispenser cover 406 rotating around that cover hinge 504, defining an angle which runs parallel to the long axis 104 of the container 102. In other embodiments, the dispenser cover 406 may be configured to rotate open, perpendicular to the long axis 104.

The presently disclosed invention may further comprise a trigger 402, which both actuates the dispenser cover 406, and actuates a food item dispenser 408. Actuating the dispenser cover 406 may comprise a direct connection between the trigger 402 and the dispenser cover 406 such that pushing the trigger 402 directly slides or rotates the dispenser cover 406 to its open position. Such a direct connection between the trigger 402 and the dispenser cover 406 may be a solid part, or a connection by means of one or more parts connected with lever or rocker connections, cams, gears, springs, or other suitable mechanism, as will be apparent to one of skill in the art. In other embodiments, actuating the dispenser cover 406 may comprise releasing a dispenser cover catch 506 such that the dispenser cover 406 springs open, impelled by dispenser cover opening means, which may be a separate spring, or a part or extension of the container 102 that is elastic and extended to exert force upon the dispenser cover 406, or may be other suitable means for opening the dispenser cover 406. In any embodiments, the dispenser cover 406 may close automatically upon release of the trigger 402 due to one or more dispenser cover closing means which may be springs attached to the dispenser cover 406 or the trigger 402, or other suitable means of closing the dispenser cover 406. In alternative embodiments, the dispenser cover 406 may need to be closed manually by the user. In some embodiments, the trigger 402 may be a protrusion that slides circumferentially along the surface of the container 102, describing an arc around the long axis 104 of the container 102, or which slides in another direction. In other embodiments, the trigger 402 may be a button that is depressed by the user, or a latch that is pressed in a direction parallel to the long axis 104, perpendicular to the long axis 104, or in a combination of those two orientations, or the trigger may be part of a trigger assembly 400, as discussed below. In some such embodiments of the present invention, the trigger 402 actuates the dispenser cover catch 506, and the dispenser cover opening means thereupon open the dispenser cover 406. In other embodiments of the invention, the user may directly operate the dispenser cover catch 506 to open the dispenser cover 406.

Upon the dispenser cover 406 opening, it has been found to be advantageous in the present invention to have the food item dispenser 408 actuated, and push one of the food items 112 out of the dispenser opening 114. The food item dispenser 408 may, in some embodiments, be actuated by means of the dispenser cover opening means, or in alternative embodiments by other food item dispenser actuating means, which may be a spring or other suitable means for operating the food item dispenser 408, and which are operably coupled to the trigger 402. The food item dispenser actuating means can operate only when the dispenser cover 406 is open. In some embodiments of the present invention, after the food item dispenser 408 has dispensed one of the food items 112 through the dispenser opening 114, the food item dispenser 408 returns to its ready position, impelled by the release of the trigger 402 releasing the food item dispenser actuating means, or by other means. The dispenser cover 406 returns to its closed position, releasing the pusher catchment protrusions which in some embodiments of the disclosed invention operate to impede the pusher plate 118 while the dispenser cover 406 is open, and by releasing the pusher catchment protrusions, the food item advancer 116 can advance the pusher plate 118 and the food items 112 further towards the dispenser opening 114 by a distance of the thickness of one of the food items 112, thus placing another of the food items 112 in the ready position to be next dispensed. In other embodiments, the trigger 402 is moved manually back to the ready position.

In some embodiments of the disclosed invention, the trigger 402, food item dispenser 408, and dispenser cover 406 may be made as a one-piece trigger assembly 400, which further comprises a trigger assembly mount 410 that attaches the trigger assembly 400 to the container 102 at the trigger assembly placement 302. In such embodiments of the invention, when the user operates the trigger 402, the trigger assembly 400 rotates at the location of the trigger assembly placement 302, and the dispenser cover 406 portion of the trigger assembly 400 reveals the dispenser opening 114 while the food item dispenser 408 both pushes the topmost of the food items 112 out the dispenser opening 114, and blocks the food items 112 from further advancing. When the trigger assembly 400 is moved back, either by mechanical or manual means, the dispenser cover 406 again covers the dispenser opening 114 and the food item dispenser 408 moves out of the way of the stack of food items 112, allowing the next of the food items 112 to advance into the ready position. In some such embodiments of the present invention, the trigger assembly 400 further comprises a trigger assembly string hole 404, through which the string 210 of a constant-force spring assembly 202 may pass.

The container 102 comprises a food item insertion opening 126. In some embodiments, the food item insertion opening 126 is the bottom of the container 102, with a bottom cap 110 which is reversibly attachable to the container 102. The bottom cap 110 may latch to the inside or outside of the container 102, or may latch into the sides of the container 102 with protrusions 120 that latch into slots 122 of the container 102, or may screw onto the container with threading on the bottom cap 110 matching threading on the container 102. In other embodiments, the food item insertion opening 126 is an opening that runs the length of the container 102, parallel to the long axis 104, with a hinge that runs the length of the container 102 parallel to the long axis 104 diametrically opposed to the food item insertion opening 126.

In alternative embodiments of the invention, the device may further comprise a cartridge, which is concentric with and narrower than the container 102. The cartridge is inserted into the container 102 aligned with the long axis 104. The cartridge may be loaded with food items 112 before insertion into the container 102. The cartridge may have a cartridge food item opening that aligns with the dispenser opening 114. The cartridge may have pusher-cartridge alignment means that align a pusher plate 118 with the cartridge as the food item advancer 116 advance the pusher plate 118 inside of the cartridge towards the dispenser opening 114. In other embodiments, the cartridge may have cartridge slots that allow the pusher plate catchments to slidably engage, protruding from inside of the cartridge through the cartridge slots, with the plurality of pusher plate retainers of the container 102.

In some embodiments, the trigger 402 actuates the dispenser cover 406, and actuates a food item dispenser 408, dispensing food items 112 from the cartridge, through the cartridge food item opening and the dispenser opening 114. The cartridge may also comprise cartridge-container alignment means, which may be slidably engaged with cartridge-container alignment guides affixed to or part of the interior of the container 102, to ensure that the cartridge is properly aligned within the container 102.

With reference to FIG. 6, FIGS. 6A and 6B illustrate an embodiment of the present invention, depicting a container 102, a bottom cap 110, and a top cap 108. FIG. 6C further illustrates this embodiment of the present invention with a cross-sectional view, taken along the transect A-A′ in FIG. 6B, further illustrating in cross-section a container 102, a bottom cap 110, and a top cap 108, a plurality of food items 112, food item advancer 116, a pusher plate 118, and sidewalls 106. Each of FIGS. 6A-6C further depict the top cap 108. It has been found to be advantageous to have the top cap 108 comprised, in some embodiments, of a moderately flexible and elastic material including but not limited to silicone, and to have the top cap 108 further comprise a pusher knob 612, a flexional region 614, and a flexible dispenser slot 618. The pusher knob 612 extends away from the container 102 and may be pressed by a user towards the flexible dispenser slot 618 at the front of the container 102. The pusher knob 612 flexes, relative to the rest of the top cap 108, at the flexional region 614, contacting with the inside surface of the pusher knob 612 the topmost of the plurality of food items 112, and pushing the topmost of the plurality of food items 112 into and out through the flexible dispenser slot 618. After the topmost of the plurality of food items 112 has been moved out through the flexible dispenser slot 618, and the user has released the pusher knob 612, the next of the plurality of food items 112 is advanced by the food item advancer 116 towards the top cap 108.

The flexional region 614 may comprise a more flexible material than the other part or parts of the top cap 108, by use of a different material or composition of matter, or the flexional region 614 may be made of thinner material than the remainder of the top cap 108, or may have its relatively higher flexibility than the rest of the top cap 108 accomplished in another manner now known or later invented. The flexional region 614 may be one band wrapping around the top cap 108, as depicted in FIG. 6A, or may be more than one discrete area of the top cap 108, as the flexional region 614 appears in FIG. 6D. FIG. 6D is a top cross-section of an exemplary top cap 108, showing a pusher knob 612, a flexional region 614, and a flexible dispenser slot 618.

The flexible dispenser slot 618 may be a simple slit across the top cap 108. It has been found to be advantageous to have the flexible dispenser slot 618 further comprise a plurality of dispenser slot flexors 620 to allow the flexible dispenser slot 618 to open sufficiently to allow the pusher knob 612 to expel the topmost of the plurality of food items 112 through the flexible dispenser slot 618.

FIG. 6E provides an exploded perspective view of an embodiment of the device 100, illustrating the bottom cap 110, the container 102, the food item advancer 116, the pusher plate 118, the plurality of food items 112, and the top cap 108, further comprising the pusher knob 612, the flexional region 614, the flexible dispenser slot 618, and the dispenser slot flexors 620.
